CFS (Cross flow separator)-  The cross flow plate pack consist of a number corrugated plates mounted parallel to each other at a close spacing. The raw water containing the floating material and suspended solids passes in horizontal direction between the plates. Laminar flow conditions are established while the water flows across the pack from the inlet to the outlet die. Laminar flow conditions are essential for the effective gravity separation of the water, the floating material and suspended continents. The course of passing from pack inlet to pack outlet, the floating material floats upwards into the tops of the corrugations and rises up the incline of the plate to the surface of the system where it is removed by a skimmer..  The sludge moves towards the bottom of the corrugations and slides down the incline of the plate. From there the sludge is collected in a hopper to be discharged intermittently through a blow off value.  Settled sludge cannot re-contaminate the treated water.
